$US50m offered for Maduro attempt: govt

The Venezuelan government has released several videos as evidence of what it claims was an assassination attempt on President Nicolas Maduro, saying the attackers were offered $US50 million ($A67 million).

"They were offered $50 million and residency in the United States," say the videos broadcast on the state radio and television network during a statement by Maduro.

According to the government, the perpetrators of the August 4 attack "received training in drone control and explosives in a farm called Atalanta," in Chinacota municipality.

Maduro said the "terrorists" called themselves "group number two, group bravo" and received orders to fly two drones with explosives to make an attempt on his life.

He also explained the drones were covered with shrapnel and sought to take the lives "of all the authorities present on the stage" during the 81st anniversary celebration of the Bolivarian National Guard (GNB).

The Venezuelan Prosecutor's Office said it had identified "all the material authors" of the attack, and the government on Tuesday revealed the identities of five perpetrators.

Among them are retired GNB sergeant Juan Carlos Monasterios, Yanina Pernia, Alberto Bracho, Argenis Valero Ruiz and Brayan Oropeza, the last two of whom are believed to have controlled the drones.
